The variety of platforms for describing models of discrete event systems brings about the problem of how these models should be represented in order to be easily shared across platforms (shared for the purposes of model validation, effective execution, model reusing,  or model integration). This study develops and implements the language DEVSML for the representation of the DEVS models. For the description of these models components, I use state diagrams, which are represented by SCXML. Actions and guards of the state diagrams are described using the language Scheme. This study also presents a visual tool for creation of the state diagrams, which is incorporated in the SmallDEVS system. For the Adevs environment, a transformer of the models described by DEVSML is implemented.
